Upstream filters for Postfix
Server1 / filter server
Postfix, ClamAV, Spamassassin
Server2 / mailboxs, webmail, www
postfix 2.1.5, Courier pop / imap, apache, squirrelmail, saslauthd
How do I get server2 to only accept inbound email from server1. While allowing my users to send email though server2. All users send email though server2 either though squirrelmail or though Eudora w/ SMTP Auth.
MX is pointing at server1 the filtering part is working great catching most of everything that is send though. I want to lock down server2 so inbound mail can not be sent directly to it.
Thanks in advance
